In another bowl, mix the chocolate hazelnut spread, butter, sugar and brown sugar. Beat together at medium speed until creamy; beat in egg and vanilla. Stir in the dry ingredients.

Shape the cookie dough into balls. Roll the balls in the sugar crystals; place the cookies on a cookie sheet about 4 inches apart, making an indentation with your thumb in the center of the balled dough. Bake for 8 -10 minutes. Remove the cookies from the oven. Quickly spoon about ½ tsp of Nutella into the center and top with a Hershey’s Hug. As the cookies cool the Hugs will melt into the Nutella.
